binations l-lereinal-tcr described and claimed.

Reference is to be had "to the accompany ing drawings, forming a part ofthis spccification, in which similar characters ofreierence ind icatccorres 'ionding parts in all the figures.

Figure l is aside elevation of one'embodiment of my invention, partsbeing in section, showing the drawing-tool in its lowered position. Fig.2 is a similar view With the tool raised. Fig. 3 is an end elevationthereol,

taken from the right i 1 Fig. 2, the glass cyl inder being broken away;and Fig. 4 is a similar view taken from the left in Fig. 2.

l0 designates a suitable base upon which is mounted a pair of plates 1111, the upper one being rotatable upon the lower and. serving as 'aturn-table. Upon the upper plate is supported a frame 1 here shown ascon sisting of upper anddcwcr members 12 13, respectively, and.intermediate vertical and inclined connecting members :14. At one endoi, the luu'izontal members are preferably mounted pairs of arms 15 15,between which extend substantially vertical rods 16 '16. Neurone end ofthe frame member 1.2 is jourrolled in suitable bearings ashatt 17, uponwhich is fixed a pair of rolls or pulleys 17 17, serving as supports,and, as here illustrated, provided with peripheral grooves.

do the gro'ove'oi each of these pulleys is socured one extremity of acable 18, which is fastened at its opposite end to a cross head or bar19, encirc ing at its ends the rods 16 Below the frame and situatedbeneath the path of the cross-head is a trough or pct 20, connected witha iurnacc 21, ada ted to contain and supply molten glass. lpon the shaft17, here shown as between the rolls 17* 17*, is

fixed a roll or pulley 22, to the periphery of improve apparatus whichis secured a cable 23, passing over a roll or pulley24, fastened upon ashaft 25, journaled in bearings near the other side of the frame andupon the member 12 thereof. The lower end of this cable 23 is attachedto a piston-rod 26, which also has secured to it a cross-head 27,operating between guides 28 28, suitably mounted on the frame. piston 29of this rod operates in a preferably vertical cylinder 36, supported.upon the lovver member 13 of the frame. Into the up or portion of thecylinder opens a pipe 31, eading through the upper portion and axiallyof the frame from some source of power, preferably a compressor orreservoir oi com pressed air. From the opposite extremity of thecylinder leads a pipe 32, which extends into one of the side outlets ofa cross-fitting 33, to the opposite outlet of which is connected aflexible pipe or hose 34. In the pi e 32 adjacent to the cross is showna va.ve 35, which may serve to either permit direct passage through saidpipe or divert the flow therefrom into the atmosphere, and near thisvalveis a shut-oil valve 36. Upon the other side of the cross inconnection with the flexible pi pc is a shut-oil valve 36. This flexiblepine 34 terminates in an elbow 37, from which depends a short section ofa pi e 38, mounted in the cross-head. Upon the lower end of thispipe-section is mounted the rotatable member 39 of a union, which ispreferably provided with a handheel 4:0 for convenience in operating it.The other member 41 of the union is formed upon the upper'cxtrcn'iity ofa drawing pipe or tool 42, tl'irough -which a passage 4-2) and whichtcrn'iinattai in a head or enlargement 44 for the purpose of taking upand holding the molten glass. Upon the drawing-tool are shown twocollars i5 45 for convenience in handling it.

From the lower outlet of the cross extends a pipe 46, which preferablypasses through the axis ol'the irameand through the center of the plates11 1 this, with the similar situation of the delivery-pipe 3i,permitting the rotation of the trams. in this pipe ad jacent to thecross is a shu valve 47, and from the opposite or upper outlet leads apipe 48, having a shut-oil valve 49 and entering the delivery-pipe inthe pipe 31 is a regulating or controlling valve 51, here shown aslocated adjacent to the cylinder, and a shut- T he 7 off valve 50, bothof which have elongated spindles extending toward the group of 'valvessurrounding the cross, so that the erably of balanced piston type andhaving its movable portion 53 located within a casing 54. It isconnected by its spindle 55 with a diaphragm 56, dividing a chamber 57.

Pressure is admitted to the upper side of the draphragm through a pipe58, leading from the pipe 31 on the piston side of the valve VJ Pivotedat 59 in the casing is a lever 60, carryin an adjustable sliding weight60,and

to W ich is secured a variable weight which, as here illustrated,consists of a chain 61. To the other end of this chain is jointed a cordor flexible connector 61, secured at its opposite end to the peripheryof a roll 62, fixed'u on the shaft 25.

In tlib use. of my improved machine the frame is rotated until the endof the drawingtool lies over the supply-trough. The tool is then drawndown until the head dips into the glass a sufficient distance to permitenough to adhere thereto to support the weight of the cylinder to bedrawn, this bringing the connected pist'on near the top of its cylinder.The valves 36, 47, and 50 now being closed while 36 and 49 are open,enough of the compressed air is admitted to start the glass from. theinside of the head. The valve 49 is now closed, and the valve 51 is setto permit the entrance of sufficient; air into the cylinder to force thepiston down at the desired speed. The controlling valve and its-chainare then set to give enough pressure on the piston to start theoperation. The valves 36 and 50 are now opened and the air admitted tothe upper side of the piston. travel downward, moving the cables overtheir supports and raisin the drawing-tool.

The air in the cylinder be ow the piston is simultaneously forcedthrough the pipe 32 and the flexible pipe 34, its valve 36 being alsoopen. As the .result, a hollow cylinder of glass will be formed upon theend of the tool the dimensions of which will be dependent upon the rateof travel of the tool and the quantity of air forced through itspassage. As this proceeds the regulatingchain of the controlling-valvewill be lowered, adding weight link by link to the lever and grad uallyopening the valve to augment the quantity and pressure of the airadmitted, and thusincreasing the rate of piston travel proportionatelyto the distance through which the tool is moved, and therefore to 'theweight of glass which it carries. When the desired length of cylinderhas been attained,

the valves 36 and 50 are closed and the valve This causes it tobring thecylinder to one side ofthc trough,

when upon turning the union by means of its hand-wheel thedrawmg-tool'1s released and the cylinder may be detached therefrom.

. It will be seen that in my improved Ina-- chine the volume of airforced into the cylinder being drawn necessarily bears a fixed ratio tothe speed at which the drawing takes place from the fact that thepower-cylinder serves to both move the tool and to displace the airwhich enters ,the passage. This results in the production of a tube offixed diameter and by virtue of the constancy of speed secured by thecontroller said tube will also be of uniform uality. The machine ismoreover exceedingly simple and convenient to operate.
